This invention relates to improvements in kitchen utensils of that typegenerally used for grating, shredding or flaking vegetables, cheese,chocolate, soap, etc.

The primary object of these improvements is the production of a devicewhich willbe highly efficient in its specific use, and much easier toclean after use than devices now commonly employed fora similar-purpose.

A further important object is to sodesign the device that it may be veryeconomically manufactured.

In carrying out the several objects of my invention I employ a bodyportion made from sheet metal and attached to a stiff wire frame,

and thus far do not depart from a common practice in the prior art.However, my

method of producing by die-stamping from a sheet of metal, an lntegrallyconnected series of strongly reinforced transverse members containingcutting edges, and spaced apart by relatively wide smoothsided,rectangular openings, through which the grated material may pass withoutobstruction, is new to the art.

It is characteristic of devices commonly employed for the purposespecified, that the grated material tends to clog up the relativelysmall, constricted or irregularly shaped interstices through which thegrated material passes. Such devices are not only difficult to use ifthe material to be grated is somewhat adhesive in character, but ftenextremely difficult to clean'after use.

The degree to which the primary objects of my invention are attained byreason of my unique construction, is attested by the fact that,utilizing a device constructed precisely as illustrated in theaccompanying drawing, a complete bar of common laundrysoap may bereduced to thin flakes in thirty seconds,

' ing drawing.

after which allparticles of the soap may be removed from the device bystriking its lower edge several times against another object,

such as a table top.

The nature of the improvements by means of which my several objects areaccomplished, will be evident by reference to the accompany- In thisdrawing:

Fig. 2 is a side view of the complete device with a portion cut awayontheline 22 of F 1 F ig. 3 is a somewhat diagrammatic, partial,longitudinal section on the line 3- 3 of Fig.1, illustrating the gratingaction of the device onthe material indicated in dotted outline, andwhich may represent a cheese, chocolate, soap, or the like,

Fig. 4'is; an end view looking at the end opposite to the handle, 1

piece of Fig.5illustrates a blank cut from a sheet i of metal, and fromwhich the body portion of the .devicemay be formed by bendingoperations, and

F'gs. '6 and 7 represent twovof the possible variations in the form ofthe cutting edges designated as 13a and 13?), respectively;

In 'manufa'cture,'the blanking out of the body portion of the device andmost of the necessary bending is produced in one operation. However, tofacilitate description, it flat blank is illustrated in Fig. 5, but withall of the necessary cutting out of the metal completed. From this flatform the portions 123 and the portions 15 are bent up at right angles,and the portions 1 1, 14a and 14?) are bent down at right angles. Theportions 15 are then crimped around the respective portions of the wireframe 11,.as illustrated in the several figures of the drawing. Thecompleted'device thus presents a series of flanged transverse members 12of Z-section, with clear, rectangular open spaces 16 between adjacenttransverse members. i The flange portions 13 and 14 projectingperpendicularly from the plane of the members 12, and from oppositesides and opposite edges of the latter, serve not only to reinforce andstiffen the members 12 and the device as a whole, but also provideknife-like edges so disposed as to function as grating knives. It isobvious that the relatively wide, open spaces 16, between adjacentmembers 12, allow the grated material to pass freely through the device,as indicated in Fig. 3, without clogging, and thus without undueforcing. This feature is, of course, also responsible for the extremeease with which the device may be cleaned after use as above set forth.1

It is to be noted that the construction and forming of the device asdescribed gives 11;

durability with economic use of material and manufacturing operations.

Although the portions of the WllG frame extending beyond the body of thedevice may be variously formed, the shape illustrated has been foundadvantageous in use of the device. Thus, the upper part of the wireframe serves as a handle which may be firmly grasped in one hand Whilethe lower part of the frame acts as a support which may be rested on anyconvenient surface.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A grater comprising a frame supporting a body portion integrallyformed with a series of parallel transverse members separated from eachother by substantially rectangular open spaces, and having opposedperpendicular flanges reinforcing said members and forming cuttingedges.

2. A grater having side portions affixed to a stiff wire support andaplurality of transverse members of Z-section in spaced relation integralwith said side portions, and present ing reinforcing and cutting flangesprojecting at right angles to the plane of said members.
